IPC: G01N27/327
Filed: 1986-12-01
Abstract: PURPOSE:To accurately measure glucose with good reproducibility, by coating an electrode system with a perforated reaction layer and respectively setting the quantity of glucose oxidase and that of a conjugated electron acceptor to 40-100U/cm<2> and 10-20mum/cm<2> per the unit area of the perforated reaction layer. CONSTITUTION:An electrode system is formed using a carbonaceous material and coated with a perforated reaction layer respectively containing a definite quantity of glucose oxidase in a range of 40-100U/cm<2> and a definite quantity of a conjugated electron acceptor in a range of 10-20mum/cm<2> per the unit area of the perforated reaction layer. When a liquid specimen is dripped on the perforated reaction layer to be infiltrated therein, glucose oxidase being enzyme and the electron acceptor are rapidly dissolved in said liquid specimen and the enzymatic reaction with the glucose in the liquid specimen advances. Since the enzyme and the electron acceptor are contained in the reaction layer in the optimum quantities, the non-uniformity or insufficiency of dissolution and reaction is not generated and stable reaction can be performed and accurate measurement can be performed with good reproducibility.

Title: Cleaning device for electrophotographic device
Inventor: ISHIDA ATSUO
IPC: G03G21/00
Filed: 1986-12-03
Abstract: PURPOSE:To stabilize a toner removing function by providing a mechanism which presses an elastic blade against a drum surface and a columnar member which clamps the curved part formed at the tip part of the blade with the drum surface. CONSTITUTION:The elastic blade 2 is compressed lengthwise when it is pressed against the surface of the drum 1. When the drum 1 rotates as shown by an arrow 25, the tip of the blade 2 receives a static frictional force generated with the drum surface and is displaced following the drum surface, and the blade part in front of the fixation part to a holder 3 curves. The tip part is clamped between the columnar member 17 and drum 1 after the blade is displaced to curve the blade part forcibly to a small radius of curvature. The curved blade restores itself to a linear state by its own elasticity and its restoring force is large as compared with when the columnar member 17 is not absent. Consequently, the press-contacting force of the blade which is generated at the start of the rotation of the drum is securely prevented from decreasing.

Title: Combination control system, and system and method for process processing
Inventor: MOTOI KOUSUKE
IPC: G06F13/12
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To provide the system which can increase the generation efficiency of an application program. SOLUTION: A communication process 6 takes in data showing the states of respective objects J1 to Jk at specific intervals of time and sends them to a common storage means. Consequently, the storage contents of the common memory 10 are rewritten at the specific intervals so as to present the current states of the respective objects J1 to Jk. Further, the communication process 6 reads the storage contents out of the common storage means at specific intervals of time and supplies them to corresponding objects. Therefore, a processing process (application program) can control those objects only by accessing the common storage means without paying attention to the procedures of communications with the respective objects.

Title: Method for measuring existing stress of structure
Inventor: MASE JIYUNPEI
IPC: G01L1/00
Filed: 1985-12-20
Abstract: PURPOSE:To make it possible to measure presence stress with high accuracy without generating a residual strain or processing strain error, by applying electrolytic processing to the surface of a structure to form an aperture part having a predetermined cross-sectional shape and not piercing up to the back surface thereof by electrochemical elation. CONSTITUTION:An electrolyte is recirculated to the surface of a structure 10 and the processing electrode held in the electrolyte in a freely reciprocating manner is used as a cathode so as to leave an appropriate gap between the leading end thereof and the surface of the structure 10 while the structure 10 is used as an anode to allow a DC current to flow between both electrodes. By this method, an aperture part 11 having the same cross-sectional shape as the processing electrode as processed. Because the stress already generated in the structure is released in the periphery of the aperture part 11, stress distribution corresponding to the presence stress of the structure 10 is generated. This distribution is transmitted to the photoelastic film material 13 adhered to the surface of the structure 10 and the film material 13 receives photoelastic effect corresponding to the stress transmitted to the film material 13. After the processing of the aperture part of the structure 10 was finished, an electrolytic processing apparatus 20 is withdrawn and the stress transmitted to the film material 13 is analyzed to make it possible to calculate existing stress.
